How to correctly route traffic from two network cards?

Question

VPN

I have a Windows 10 ltsc pc with two network cards.
1. The network card is normal Internet access. (Static IP)
2. The network card is connected to the pfsense VPN client and all traffic goes purely through the VPN. (Static IP)
VirtualBox installed.
Required:
For the default gateway to be 1 network card and all traffic to go through it.
2 network card should only release VirtualBox machines to the Internet.
At the moment, all my traffic goes as it wants - either in network 1 or 2.
Tell me where to smoke? What are the means to solve the problem?

Answer 1

In VBox on machines, make a network bridge to the second card. Then the virtual machine will have a purely 2nd network and she will not know anything about the first

Answer 2

Youtube is full of such answers.... about setting up a virtual box for 2-3 virtual machines....
